We have to consider what these changes are, what are their laws, and what their ultimate tendencies; thereby adding a theory of motion to our theory of equilibrium—the Dynamics of political economy to the Statics.

In this inquiry, it is natural to commence by tracing the operation of known and acknowledged agencies. Whatever may be the other changes which the economy of society is destined to undergo, there is one actually in progress, concerning which there can be no dispute. In the leading countries of the world, and in all others as they come within the influence of those leading countries, there is at least one progressive movement which continues with little interruption from year to year and from generation to generation; a progress in wealth; an advancement of what is called material prosperity. All the nations which we are accustomed to call civilized, increase gradually in production and in population: and there is no reason to doubt, that not only these nations will for some time continue so to increase, but that most of the other nations of the world, including some not yet founded, will successively enter upon the same career.
